HEAT-INSULATING CASING FOR BOTTLES.

Application tiled August 3, 1911.

Specification of Letters' Patent.

Patented June 18, 1912.

Serial No. 642,110.

To all whom 'it may concern:

Be it known thatl l, Pnnmvar. RArMoNn 'Soirvrnnm a citizen of the United States,

residing at- Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Heatlnsulating Casings for Bottles, of which the following is a specification.

This invention relates to liquid containers of the class in which the container is insulated from the temperature-condition of the atmosphere, and itA has for its object to provide anarticle of this kind the arrangement and construction of whose parts shall be such that, while a clear airspace will be leftl substantially all around the inclosed bottle or` the like container so as to insulate its contents from the temperatorif-condition of theatmosphere, said bottle will be held within its inclosing shell in such a way that itI will not only be fixed and firm therein but at the same time be very considerably protected from breakage should the container fall or otherwise receive some violent jar or blow, and also incapable of working or being jai-red loose.

A further object is so to construct a container of this kind that it will be especially proof against its contents finding their Way into the space betweenihe vessel and its shell, and so that it may be readily taken apartv for cleaning, if desired or necessary, or for the purpose of replacing the bottle should the same become damaged or broken.

A still further object is to construct the container so'that it may be filled or emptied with facility and so that the stopper for the said bottle may be held securely and hermetically in place to prevent the escape of its contents,

My invention has been fully illustrated in the accompanying drawing, wherein,

Figure l is a vertical sectional view` showing the bottle partly in elevation; Fig. 2 is a plan view of the lower seat for the bottle; and, Fig. 3 is a sectional detail view of a modification.

a designates the bottle of usual form and made of glass or the like.

o is the shell or easing in which the bottle is disposed, the saine standing spaced from the bottle at substantially all points and being closed at all points except for the opening c which coincides with the opening or passage d of thehottle; said shell conforms in shape to substantially the shape of the bottle, as shown.

Ihe shell is made in two sections o and o", each section being drawn or otherwise formed from sheetanetal. The open or upper end of the lower section is formed with a coarse screw-thread e, and, below said thread, witha surrounding horizontal groove the upper section has its lower edge-portion g formed as a cylindrical lip expanded to a somewhat larger diameter than the body of said section and, immediately above said lip, said upper section is formed with the coarse screw-thread 71. When the parts or sections of the shell are assembled. the upper section slips over the lower section and when one `is now turned relatively to the other a screw-thread connection is formed between them by the interengagemcnt of their threaded portions. In the groove f is fitted au elastic crosssectionally round rubber ring 2' over which the lip-g wipes when the sections are assembled, hermeticallj' sealing the joint between them at this point.

The lower section is formed on its bottom, which is otherwise flat, with an annular marginal bead or flange, affording a seat and reinforcing the bottom: above the bottom at a suitable dis-tance themetal of the lower section is crimped inwardly to produce an internal flange or be'ad L', which further reinforces the bottom part of said section. On this bead or flange rests the marginal part or edge of a seat Z which is a disk of metal havingits central part drawn downwardly, as at. mi. to form a` socket for the bottom ot' the bottle, its flange-portion a being provided with theapertures 0. The seat- Z has preferably but limited contact with the bead l: whereby to reduce the conductivity atI this point, and by shaping the seat Z as described it not only serves to prevent sidewise movement of the bottle but is strengthened against the downward pressure of the same,

The necleportion of the upper section b is formed with a coarse screw-thread 7), and above said thread'with an internal annularl groove g. Said upper section has the' edge@ portion thereof aroundits opening o turned back on itself continuously to form a `cylindrical bead 1' which serves not only to imi part a finish to the edge of said o enit/1g but coacts with a shoulder s at the ot er side of said groove to retain in place a seatlt consisting of an elastic rubber cross-sectionally round ring.` By this construction the ring is normally retained in the groove, although it may be removed to be replaced by a new. one when it ceases to be serviceable. 'The seatt bears continuously on the mou-th of the bottle in the assembled relation of the parts, y

the screw-thread connection between the shell-sections holding the bottle under pressure between said seat'and the seat Z, so that the bottle stands firm and stable within the shell. The mouth of the bottle being of somewhat less diameter than the seat 1f,it

projects slightly into thelatter and is thus insured againstv sidewise movementv relatively thereto. l

To hold in place the stoppe-r for the bottle, I-provide the cap v), having the .coarse screw-thread 'w to mate with the screwthread 79 of sect-ion b; when this cap is screwed down it retains the stopper (m) against accidental displacement.

Fig. .3 shows a modification designed to.

reduce to substantially m'l the conductivity at the point where the lower bottle seat is.

supported by the section b2. Here the said seat, designated y, has a grooved rubber rin-g .e fitted over and continuously around-its edge, the said ring resting on the bead Ic of the shell-section b2. Being of rubber, this ring augments the insulation of. the bottle from the shell and at the same time cushions the seat.

' bottle through the medium of the seats Z and the airspace around the bottleis entirely sealed off from the atmosphere. l y

Having thus fully described my invention, what I claim and desire to secure byr Letters Patent is:

I. In combination, a bottle, a shell receiv ing and shaped toconform substantially-to the shape of the bot-tle and having an opening coinciding with that at the bottle-mouth` but being otherwise closed atsubstantially Loaasa? all points, said shell being spaced from the bottle at substantially. all points and being divided horizontally into t-wo sections sepa-` rably interlocked together, an upper annular seat above the mouth of the bott-le around the lopening therein and interposed between pressingcontact with the bottle interposed between them, substantially' as described.

2. In combination, a bottle, ashell rece1ving and shaped to conform substantially to theshape of the bottle and having an-open ing coinciding with that of the bottle but being otherwise closed at substantially all" points, saidshell being spaced from the bottle at substantially-.tall points, means, between fthe bottle and shell, for maintaining them in spaced relation to each other, said .shell being divided horizontally 4into two sections having anA interlocking connection between them and -one of said sections having a cylindrical lip and the other a groove coinciding with said lip, and an elastic ring arranged 1n said groove and bearing cont-1nuously'against said lip, substantially as described.

3. In combination, a bottle, a shell receiving andshaped to conform substantially to the 'shape of the bott-le and'having an opening coinciding with that of the bottle but being. otherwise closed at substantially all points, said shell beingspaced from the bottle at, substantially all points and having an internal horizontally arranged projection near its bottom, and seats interposed one between the top portion of the bottle and shell and aroundthe opening of the ormer and the vother under the bottle and resting on said projection, the latter seat beingja disk of stiif material having its middle portionl drawn downwardly and forming a socket receiving and fitting the bottom ofthe lbottle, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
